A Thursday afternoon delivery of a power shutoff notice led to the arrest of a Quincy couple for allegedly growing scores of marijuana plants.

Police Capt. John Dougan said Hao Vu and Annie Vu, both 37, of 228 Norfolk St., were charged with marijuana trafficking conspiracy to violate state drug laws and other offenses after police found 63 pot plants growing under heat lamps in the couple’s basement.

The Vu’s are also charged with disorderly conduct, resisting arrest, and child endangerment of their four children, who are all 8 to 12 years old. Annie Vu is also charged with misleading police.

They’re scheduled to be arraigned Friday in Quincy District Court.

Dougan said officers discovered the pot operation when they arrived at the Norfolk Street house in the Wollaston neighborhood at 12:35 p.m. Thursday, to serve a utility shutoff notice that the Norfolk County Sheriff’s Office had gotten from Quincy District Court.

Dougan said that when they opened the door, officers smelled “an overwhelming odor” of marijuana, and felt heat from the basement. When they saw the pot plants and heat lamps, they left and returned with a search warrant.

A man who answered the door left the house after a brief exchange of words. Officers then found 63 pot plants in the basement and 18 small plants elsewhere in the house.

From a license plate alert, police shortly afterward found the man, later identified as Hao Vu, at an Adams Street apartment, where they also found the children and a female, later identified as Vu’s wife, Annie Vu.

Dougan said Hao Vu ran from the apartment and was chased and cuffed by officers. Annie Vu was then arrested.

Both arrests were made at about 2 p.m. Dougan said the Vu children were taken to Quincy Medical Center and are in the custody of the state Department of Children and Families.
